Patco Electronics was founded in the fall of 1992, for the purpose of providing the electronics industry with state of the art battery management tools spanning the chemistries employed in secondary batteries. The first product was a battery manager for lead acid batteries designed around the Unitrode 3906 lead acid controller. From there Patco has expanded the lead acid line to include higher current managers for larger batteries, and algorithms for unique construction of lead acid batteries. NiCAD and NiMH managers designed around specialized controllers came next. A third product line addresses the medium prismatic Lithium Ion batteries manufactured by Saft America.
